とを備えたテープレコーダー。 A tape recorder with a bidirectional playback function includes a response switch that closes in response to mounting a cassette at a playing position and opens in response to an eject operation, and a first control transistor that becomes conductive when the response switch is closed. , an electromagnetic means that maintains the mounted state of the cassette by being activated through the first control transistor, a differentiating circuit that outputs a differential pulse by switching a reversing switch in conjunction with reversing operation of tape running, and the differentiating circuit. a second control transistor that becomes conductive in response to a differential pulse output from the second control transistor to turn the first control transistor into a non-conductive state; and a selection switch that prevents the second control transistor from becoming conductive in response to the differential pulse. tape recorder.
